  • Work on customer prediction problems including pricing, forecasting, and segmentation
  • Develop models using Python and SQL on large-scale datasets
  • Own the full model lifecycle from data extraction to deployment and monitoring
  • Collaborate with Product and commercial teams to drive decisions


Candidate Profile

  • 1–2 years industry experience as a Data Scientist
  • Strong academics (Russell Group or equivalent, STEM degree)
  • Experience building ML models in Python and SQL
  • Background in customer prediction (pricing, forecasting, segmentation) or credit risk
  • Curious, high-energy problem solver with strong ownership mindset


Key Details
